Percore Pro is an auto-renewing subscription billed through your Apple ID. You can cancel any time in the App Store; cancelling stops the next renewal and you keep Pro until the period ends.
What Pro is not
Pro does not unlock the exercises, your scores, your streak, your radar, or your daily reading. Those are free, and gating them would mean selling you back your own progress.
Billed weekly, a year of Pro is $519.48. The yearly plan is $39.99 — about what four weeks cost. The weekly option exists for trying Pro without committing a year, not because it is the better deal, and it would be strange not to say so.
Prices are in US dollars. Apple sets the equivalent in your own currency at launch, and the App Store shows you that figure before you buy.
About the subscription
Is there a free trial?
Not at the moment. When there is an introductory offer on the store product, the app will say so on the button itself rather than in the small print.
What happens if I cancel?
Pro features stop at the end of the period you have paid for. Nothing you have measured is deleted, and the free daily practice continues exactly as before.
Why is the weekly plan so much more than the yearly one?
Because they are for different things. The yearly plan is the price of Pro for someone who intends to keep the practice. The weekly one is for trying Pro properly without committing a year — convenience, priced as convenience. If you already know you want it, take the year.
Can I buy Pro on the web?
No. Percore Pro is bought inside the app through the App Store, so your subscription is managed in one place with everything else on your Apple ID.
